Wood-plastic wall core plate extrusion device and processing technology

The invention belongs to the technical field of wood-plastic plate production, and particularly relates to a wood-plastic wall core plate extrusion device and a processing technology. The wood-plastic wall core plate extrusion device comprises a base, a driving device, a transmission box, a combustion furnace frame, a heat preservation shell, a hot melting furnace, a conveying cylinder and a screw rod; the interior of the heating cavity is slidably connected with a movable ring; cleaning rings are fixedly connected to the outer side and the inner side of the movable ring; a lead screw is rotationally connected into the heating cavity in the length direction. The bottoms of the two ends of the heating cavity communicate with slag outlet pipes. A power mechanism in a transmission box drives a lead screw to intermittently rotate forwards and backwards, a movable ring is driven to do reciprocating motion in a heating cavity, two cleaning rings are used for scraping impurity solidification layers formed on the sur
